Configure nginx as a reverse proxy for a node js application, routing root requests to the back end while serving static content for improved performance.

Learn how squid works as a proxy and caching server, improving performance, controlling access, and hiding client IPs, with installation on Ubuntu, starting services, and optional from-source compilation.

Explore the squid.conf sample to start a squid server and configure a local proxy; understand directive types and how http_access and acl control access.

Learn how to configure squid ACLs to control client access and web resource permissions, including port tweaks (3128 and 80) and restricting to local hosts like 127.0.0.1.

Learn to use the http_access directive with ACLs to control squid proxy access by defining source and destination IPs, domains, and ports, and applying a catch-all deny.

Configure access controls to deny media files with ACLs and regular expressions, and optimize web performance by configuring Squid caching, cache directories, and proxy settings.

Examine how to set up a Linux database server. Compare relational, NoSQL, and in-memory engines, including tables and joins, documents and collections, and data stored in memory.

Learn MySQL installation on Ubuntu and CentOS, including choosing MySQL server or MariaDB. Secure setup with mysql_secure_installation to set root password and disable remote access, remove test database.

Learn basic MySQL commands to set up a bookstore database, show databases, grant access, use the database, and perform insert, select, update, and delete on authors.

Install and configure phpMyAdmin on Ubuntu with Apache, access localhost, and manage a bookstore database by creating an authors table with name, phone, address, and inserting records via GUI.

Install MongoDB and explore document-based storage, collections, and JSON data; learn to insert, find, and query with filters, inspect with pretty, and understand the NoSQL paradigm.
